The present invention relates to a combined total heat / sensible heat exchange element that can be used in combination to perform both total heat exchange and sensible heat exchange.

  In general, the content of carbon dioxide contained in the air in an indoor space gradually increases with time due to respiration of living organisms. Since the increased carbon dioxide content impedes the breathing of living organisms, the air in the indoor space needs to be replaced with fresh air in the outdoor space as needed.

  Usually, the air in the indoor space is forcibly exhausted to the outdoor space by a ventilator such as a blower, and the air in the outdoor space naturally flows into the indoor space by opening the window.
